The Use of Dynamic Vocal Tract Model for constructing the Formant Structure of the Vowels
نویسنده
چکیده
This paper discusses the new method of constructing the dynamic vocal tract model. It consists of two dynamic parts: the voice source and filter components. Each of these parts has their own dynamic features and resonant frequencies. Their interaction leads to the short-term phonetic effects. The method of obtaining frequency characteristic of the filter component by processing the real speech data is suggested. It allows constructing the formant structure of the vowels and their variations. On the example of the realization of the stressed vowel /a/ the formant structure using the new method is detected.

Objective: One of the parameters showing the correct phonetic and phonological development is the correct and clear articulation of vowels is achieved by changing the shape of vocal cords through altering the height and position of the tongue and the movement of the lips and jaw. The tongue’s height and position are the basis of the production and difference of vowels. In other words, the raw s...

Objective: Vowels are the center of syllables while formant structures are one of the most important acoustic characteristics of speech sounds that help in their articulatory and perceptual aspects. Formants represent the shape and size of the vocal tract. There exist trivial differences between the vocal tracts of different people due to which the formant structures of a vowel in one person ar...

Background and Objective: One of the most important physical properties of vowels is their formant structure. One of the most obvious speech errors in hearing-impaired children is vowel errors. The present study aimed to determine and compare the formant structure of Persian vowels in deaf and cochlear implant children in the age range of 4-7 years. Materials and Methods: This descriptive-anal...

In the present study Dutch vowel formant characteristics of laryngectomized tracbeoesophageal speakers are investigated.. Both vowels in CV nonsense syllables (/al, Iii, and /u/), and vowels of stressed syllables in read-aloud text are studied. It appeared that in the nonsense syllables the first formants were comparable to those ·of normal speakers, but that the second formants were higher tha...

Aim: To investigate the characteristics of vocal tract resonance in Hindi Esophageal Speakers. Methodology: Five normal Hindi speakers and five Hindi esophageal speakers participated in this study. They were asked to produce the three corner vowels /a/, /i/, and /u/ in the three different conditions like nonsustained, sustained and word level. The average first three formant frequencies F1, F2,...
